Arnold Schwarzenegger said on Friday that he will not return as host of The New Celebrity Apprentice, and blamed Donald Trump for the reality show’s recent poor performance.

On Saturday, in response, Trump said Schwarzenegger had been “fired by his bad (pathetic) ratings”. Schwarzenegger replaced the president as host of the show, but Trump remained as an executive producer.

The president taunted Schwarzenegger for the show’s recent poor performance in the ratings, even mocking him during an address at the National Prayer Breakfast.

“With Trump being involved in the show, people have a bad taste and don’t want to participate as a spectator or as a sponsor or in any other way support the show,” Schwarzenegger had said.
